We have written about an app that disables the auto-tilt on the BlackBerry Storm before and there is another you should check out.

While auto-rotate is a good thing, there are certain situations where you just don’t want it. A common example involves when you have a Wallpaper that looks great in portrait mode, but not in landscape mode, so you want your homescreen to be locked in a certain orientation.

StopTilt gives you the ability to choose when you want your screen locked. It’s a small app that enables users to lock the orientation of screen in their preferred mode. The best part is that separate apps can be locked in different orientations, such as email in portrait and browser in landscape. Also, unlike Storm Rotation Wizard, StopTilt remembers your preferred orientation across device resets.
